Name: Miller Range 05035 This is an OFFICIAL meteorite name. Abbreviation: MIL 05035 Observed fall: No Year found: 2005 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 142.2 g
Macroscopic Description: Kathleen McBride
The exterior has about 95% black, shiny fusion crust. The interior is pinkish-tan in color with no rusting. The rock is moderately hard and has an unusual granular texture with a vague resemblance to granite. There are numerous inclusions; linear white features a few mm in length, melted appearing black, glassy inclusions with an iridescent "peacock ore" opalescent sheen, a transparent, glass like mineral, and a few clay-like powdery areas.
Thin Section (,2) Description: Tim McCoy
The section exhibits an unbrecciated texture of coarse-grained (several mm) pyroxene and maskelynite with interstitial sulfides, iron-titanium oxides, intergrowths of fayalite-silicate-augite, and other late-stage glasses and minerals (including BaO-enriched potassium feldspar). Pyroxenes are strongly zoned and include pigeonites and augites with a range of compositions Fs31-55Wo15-42 and Fe/Mn of ~60. Plagioclase is An83-92Or0-2. The meteorite is a lunar basalt, although it exhibits some properties (e.g., maskelynite) unusual among known lunar samples.
